Meet István Biró
István Biró, known to the chess world as Playitclean, is a Hungarian blitz enthusiast with a well-earned reputation for grinding down opponents. While he keeps a toe in daily, rapid, and bullet, his heart belongs to blitz, where he has played more than 4,000 games and climbed to a peak of 2289 (2026-09-10). His blitz journey is best told through the numbers:
.Style and Stamina
Playitclean is not the flashiest player on the server, but he is one of the most persistent. He wins 61.23% of his games as White and 52.93% as Black, and his comeback rate of 80.67% suggests he never stops believing. Even after losing a piece, he still wins 54% of the time. His longest winning streak is a blistering 20 consecutive games, and he is most dangerous at 1:00 AM, which should worry anyone who queues up against him late at night.
Openings
His repertoire is built on classical bones. With Black he regularly reaches the French Defense and the Caro-Kann Defense, and with White he favors the Queen's Gambit Declined and the Closed Sicilian. He also has a soft spot for rare setups like the Australian Defense and the Amazon Attack. His opening win rate chart shows a player who knows his lines and trusts them:
.Rivals and Revenge
Every player has a personal scoreboard, and Biró's is a tale of two extremes. Against lorandchess he has a perfect 32 wins in 32 games, and against herr_general he is 20 for 20. But mllerke has his number, leading their series with 9 wins to 6 losses and 8 draws. Those are the rivalries that keep the blitz arena interesting.
The Long Game
With over 2,100 blitz wins and a peak of 2289 (2026-09-10), Biró has proven that clean, patient play still works in a fast time control. He delivers the first check in nearly 57% of his games and converts those into wins almost 65% of the time. He rarely resigns early, reaches the endgame often, and makes the clock work for him, one careful move at a time.
